Robert Miller, a real estate investor and marina owner based in Palm Beach, has purchased a home within the Mar-a-Lago Security Zone for $25 million. The property is located at 143 Clarendon Avenue and was acquired from Marcia and William Rickman Jr., according to public records.
The Millers financed the purchase with a $14 million loan from Taylor Made Lending. Carole and Brett Koeppel of Sotheby’s International Realty handled the listing, with Carole Koeppel representing the buyer.
Miller owns Jupiter Pointe Club & Marina in Tequesta and leads MLR Management LLC. He often invests in real estate alongside his son, Myron “Mosie” Miller. In recent years, Mosie Miller sold a mansion in Palm Beach Gardens to BET co-founder Robert Johnson for $20 million in 2023, followed by another sale of an oceanfront mansion in Palm Beach for $68.1 million later that year.
In 2021, Robert and Linnette Miller sold a lakefront mansion to developer Todd Glaser for $23.8 million; Glaser later resold it for $31.7 million. The couple also owns a Bear’s Club estate at 150 Bear’s Club Drive in Jupiter, which they bought for $10.7 million in 2021.
The house on Clarendon Avenue measures about 5,800 square feet and includes five bedrooms, four bathrooms, one half-bathroom, a pool, and separate staff quarters. Built in 1924 by architect Maurice Fatio, it sits on 0.6 acres of land.
Clarendon Avenue marks the upper boundary of the Mar-a-Lago Security Zone—a neighborhood that has seen increased luxury real estate activity since Donald Trump’s election victory in 2024. In the months following his win, seven properties were sold within this area totaling over $118 million as buyers cited security measures and proximity to influential figures as attractive features.
The Rickmans’ home—known as “Villa Dolce”—sold at its asking price after three months on the market.
William Rickman Jr., whose family owned Delaware Park racetrack and casino for decades before selling it to Clairvest and Rubico Gaming in 2021, continues to hold significant property interests on Palm Beach island. The Rickmans also own an oceanfront mansion at 1055 North Ocean Boulevard purchased for $13.1 million in 2016; sources indicate this property may be part of billionaire Charles Simonyi’s efforts to assemble an expansive estate nearby.
